Abstract
Crystalline and magnetic structure as well as the interlayer exchange coupling in MBE grown Fe/FeSi multilayers are investigated. From conversion electron Mössbauer spectroscopy and ion beam channeling measurements the spacer FeSi material is found to be stabilized in a crystalline metastable metallic FeSi phase with the CsCl structure. Strong non-oscillatory interlayer exchange coupling is identified with magnetometry and synchrotron Mössbauer reflectometry. From the fits of the time spectrum and the resonant ϕ—ϕ scans a model for the sublayer magnetization of the multilayer is deduced.
